There is capacity difference between the two cells and they are not the rated 900mAh, the best one is more like 800mAh

[size=+3]Conclusion[/size]

There is a significant capacity difference between the two cells, i.e. they cannot be used in series. Actual capacity is fairly normal for average quality batteries in this size.
